I installed a valve on the macerator hose because of the fact it filled every time I dumped using the regular hose and dump valves. Because it filled it had to drain and therefore I felt that waster water was sitting in it all the time.

We have now lived in and with out Seneca and its equipment for 2 years. During that time we have learned to use many of the systems. It was actually just this last Summer in our travels to the Northwest that I really started using the Macerator hose to dump. Now, I use it quite often, but I wouldn't say 100% or even 80%.

I did not have enough clearance to thread the ball valve on so I had to go with two slip on nipples and a short section of reinforced clear hose. A bit longer than desired, but works well to isolate the macerator hose from the junction box. Should be standard fitment from the factory.

I had the same issue with the ball valve clearance. Would have liked to use clear hose but could not find any locally. Also, purchased a 1.5" mnpt plug and threw it in my spares locker. If some worst case scenario ever occurs, I'll just plug it at the box and use the conventional hose until I get home

I have a portable macerator for my NP 5r. Glad to have it, and glad you posted, thanks! I never gave it a thought about leakage. Always thought the OEM valve would have been good enough of me too. Put the removal cutout valve on the list. My issue is with distance from macerator to tote. I put the blue tote in the back of the pick-up and macerate up into it. With the same style of discharge fitting (hand held) I am normally several feet from the macerator shut off toggle switch. Still figuring that part out. It has made it easy when the dump station is half mile away.

Jayco must have learned from their mistakes. On my 2018 Pinnacle with the Macerator option they installed a blade valve before the pump so it can be isolated if need be, and still able to use a standard 3" hose to dump the tanks.
(I will get some pictures posted in a day or two)

We have the same trailer and I was going to post the same thing. Shocked they would have ever sold it without a pull valve although I shouldn't be.

Found a foot of the braided tubing at Lowe's. First choice Ace did not have any. Had to heat it up with a heat gun to get it to slip on the barbed fitting; it's never coming off without cutting it. I tried removing the valve handle from the ball valve but couldn't (if you could, it would screw on).
